This is a new blend of TTTF that my local seed supplier is selling as a mix of all 3. The LS stands for lateral spread. The tech sheets look very good on these variates of grass. They have spreading properties similar to bluegrass. Just wondering if anybody here has had any experience with them yet? I am going out tomorrow and going to aerate and seed 2 lawns with this new seed. Will be interesting to see how well it does.
